Yet Another Voice Module (Sphinx + Alexa)

d3r

If I already have the alexa voice service set up on the pi is there an ‘easier’ way of setting this up or would it be better to start from scratch?
I’ll of course back up my sd card before playing with this.

If you already have Alexa set up, then you should have all the required bits. Just update the configuration with your productId, dsn, clientId, clientSecret, alpnVersion, vlcPath, vlcPluginPath (all of which you acquired when setting up Alexa). For first run, I’d try to do serveronly mode so you don’t have to mess with the electron node version disparity.

node serveronly

then open a browser on the pi @ http://localhost:8080. If this works, then follow the Installation Notes.

Thank you, I got till that part and the modules are currently loading. Your module and 2 others haven’t loaded yet. How long should it usually take?
I am using the firefox iceweasel browser.
Edit: I reloaded the page and not all my modules are loaded except the voice one. Which makes sense because I haven’t run the npm install from the module directory yet. Will do that and post back.

I was able to set up the module but I think I did a few things wrong. I think I have the vlcPluginpath wrong in my configuration. I am not sure where it is located. I believe it is here "vlcPluginPath: ‘/usr/lib/vlc/plugins’ " but I am not sure what exacly I should be looking for. When the module loads, there is currently nothing under the module. If I reload the page it switches to “loading…” and is stuck on “loading…”
Also , once I run node serveronly and open up the localhhost page the voice module does start to load but I get the following error:
`
Listening for transport dt_socket at address: 5005
Unable to run Alexa Java Client: Error: ENOENT: no such file or directory, open './magic-mirror-voice/alexa-certificate-generator/certs/server/node.key

I went to that directory and the files do exist. I used the script to generate them. My understanding is sphinx is working but there’s something wrong with the alexa part. I’m not really sure what I should do next. I’ll keep playing with it, hopefully I’ll get it to work.

Full log here:

From the logs this seems to be true. Thanks for the log, it makes debugging much easier. As mentioned in OP, my life is pretty hectic right now. I’m hoping to have some chance to look into this over the next week but may not be able to provide the optimal feedback cycle for you. Thanks for the patience.

Do you have the optional sslKey entry in the config? If you are autogenerating all the keys, I would remove all the //optional values from the ssl configuration. May be a red herring but all I can think of w/o my computer.

d3r

@whyjustin Thank you. I understand you’re pretty busy with your familly so no rush.

You were correct about the optional ssl. I commented it out and was able to get to the alexa registering part
Register Alexa Java Client by navigating to https://localhost:5555/provision/143d3e3b67c6577291228ff9
Now the problem is that the module is not registering. I cannot connect to that link if I put it in a browser. Also, I think it should be localhost:3000/provision/... because that’s how the alexa standalone app registration works but I could be wrong.
I played around with the config.
port: 5555,
serviceUrl: ‘https://localhost:5555’, // if I change this to port 3000 I get an error /
redirectUrl: ‘https://localhost:3000/authresponse’, // changing this port still returns https://localhost:5555/provision/143d3e3b67c6577291228ff

Again no rush, this can wait.

This is a long shot since you’ve setup Alexa already, but are you using a browser on the pi to connect to the site? If not you would have to replace localhost with the pi’s IP/Hostname

Also, I think it should be localhost:3000/provision/… because that’s how the alexa standalone app registration works but I could be wrong.

The oauth service can run on any port, I believe that 3000 may been taken by another process on my raspberry pi (either by Magic Mirror or something else) which is I why I used 5555. I think there is some redundancy in the three options (port/serviceUrl/redirectUrl) but it is required to keep the same port and hostname on all three. If you choose to keep 5555, you will have to update the Alexa settings that you previously set up to indicate the proper port:

Thank you.
Changed the port on the amazon website and I got it to work.
Your module is awesome! This is really good.

Thanks, good to hear it’s working. Let me know if you have any other difficulties or feature requests. As mentioned to @cowboysdude, it is easiest for me to track these through GitHub Issues. Cheers.
